What is Service Oriented?

Service-Oriented Development

What about JSON, REST, etc?Visual Studio 2008 and .NET 3.5 provide seamless support for all of the protocols and techniques popular in Web 2.0-style applications.

Visual Studio 2008 provides visual designers, debugging and profiling for WCF and WF. Numerous project items support being creating to support service oriented architectures.

What about tool support?

Services are often used to implement pattern-based behavior and/or business rules. Visual Studio 2008 makes this type of development much easier by providing an integration between Windows Workflow and Windows Communication Server.

Workflow and Services

Demands on services are getting more and more complicated – what happens when SOAP isn’t enough?

The Challenge

The SolutionWindows Communication Server (WCF)Visual Studio 2008 integrates this framework throughout its project system and features. To make implementing the logic behind these services more productive, Visual Studio 2008 also integrates Workflow Foundation – an all purpose framework for creating workflow driven applications and libraries.

Web

Creating and maintaining a test client for WCF services is time consuming and tedious.

The Challenge

The SolutionVisual Studio 2008 includes a feature that inspects a WCF service and automatically generates a client for it. Because this client is automatically generated each time, it is always up to date.This client tools supports complex service contracts, so it is practical for even the most demanding WCF services.

SOAP, XML, etc enable me to expose a service. But what is the best way for me to implement it?

The Challenge

The Solution

Visual Studio 2008 and .NET 3.5 enable many new ways of hosting Workflow Foundation applications.Also included are new activities that can be used to either consume or expose WCF services.

Developing workflow-driven applications is a different paradigm, this makes debugging difficult.

The Solution

Visual Studio 2008 enables the same debugging experience that developers have always enjoyed for Workflow Foundation applications. Breakpoints can be set on workflow elements just as though they were functions or methods in source code.

User Experience ProductivityCollaboration

Web 2.0-style applications are very likely going to be the client of choice for many WCF services

The Challenge

Breakthrough User ExperienceAJAX enabled services Web

The SolutionVisual Studio 2008 and ASP.NET provides an enhanced ScriptManager that allows calls to WCF and ASMX services. Using attributes, WCF services can expose themselves through REST or JSON. This further ensures that Web 2.0-style applications can easily invoke WCF services.

Syndication is very popular and an ideal way to spread the use of your applications.

The Challenge

Collaboration WCF Syndication Services Web

The SolutionVisual Studio 2008 provides a project template that creates a syndication based WCF project. This project type enables you to immediately expose a RSS or ATOM based feed.
